ZWO ASI183 PRO COOLED USB3.0

Introducing the ZWO ASI183 PRO COOLED USB3.0, the most sensitivie cameras in ZWO history. Peak Q.E. of the mono sensor reaches 84%!

The ZWO ASI183 PRO COOLED USB3.0 uses Sony’s back-illuminated Exmor R technology, giving it excellent Deep Sky performance. ZWO ASI183 PRO COOLED USB3.0 QE peak reaches a remarkable 84%. In Ha channel, QE is still a over 60%.
Having high QE means more of the light that enters your telescope and reaches the sensor is actually used. With 84% peak Q.E. and no less than ~50% within the visible spectrum, the ASI183 will utilize a high percentage of the light that reaches it, improving your signal quality.

In the astronomic application field, Sony IMX183CLK-J (monochrome) and IMX183CQJ-J (color) sensors uses a very high sensitivity back-illuminated structure with high resolution 2.4 μm square unit pixel. The optical size is 1 inch.
The ASI183 cameras have a very large full well capacity（15000e） for such small pixel size, 1.6e read noise @ 30DB, and 12stops dynamic range @ Gain=0. For maximum performance in astrophotography,the ASI183 Pro camera includes a 256MB DDR3 memory buffer to help improve data transfer reliability. Additionally, the use of a memory buffer minimizes amp-glow, which is caused by the slow transfer speeds when the camera is used with a USB 2.0 port.

Fast FPS can be used in solar and lunar imaging, as well as for live viewing/EAA.The high speed readout may also be used for real-time focusing, true lucky imaging of double stars and other small objects, planetary imaging of the major planets in the solar system, and much more.

The ASI183 Pro has a 2-stage TEC cooling system that enables deep cooling (40°C-45°C below ambient). The cooler requires an external power supply, which is not included with the camera.
